Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber paper, in particular to a glue dipping device for carbon fiber paper. Background Art

[0002] Carbon fiber paper refers to a functional reinforced material with carbon fiber as a reinforcing agent. The matrix is ​​natural pulp or synthetic pulp, supplemented with adhesives and fillers to obtain a paper-like composite material through a papermaking process. In the dipping machine for manufacturing carbon fiber paper, such as the H1400 dipping machine, two press rollers are arranged above the outlet of the dipping tank in the dipping machine. After the carbon fiber paper is dipped in glue, the upper and lower sides of the carbon fiber paper will be pulled and squeezed by two mutually parallel press rollers, which are mainly used to closely fit the carbon fiber dipping liquid and pulp together, thereby ensuring the quality of the produced carbon fiber paper. In addition, the two mutually squeezed press rollers can also remove the excess dipping liquid on the carbon fiber paper through the extrusion force. The frame of the existing H1400 dipping machine Two symmetrical guide rails are upright and fixed on both sides, and both ends of a paper pressing roller are rotatably installed on the two guide rails respectively. The other paper pressing roller is arranged parallel to the first paper pressing roller, and the two ends of the upper paper pressing roller are respectively lifted and installed on the two guide rails. A hydraulic cylinder is fixedly installed on the top of the two guide rails, and the piston rod of the hydraulic cylinder is vertically downward and rotatably connected to the upper paper pressing roller. That is, the upper paper pressing roller can be driven to rise and fall by the extension and contraction of the piston rods in the two hydraulic cylinders, so as to adjust the distance between the two paper pressing rollers. Because the upper paper pressing roller often needs to be adjusted up and down, it is not connected to the output shaft of the motor in the glue dipping machine. Only the lower paper pressing roller and the output shaft of the motor in the glue dipping machine are fixedly connected through a coupling.

[0003] As we all know, the deflection direction of carbon fiber paper depends on the pressure and direction applied by the two rollers. However, in the H1400 type dipping machine, only the lower pressing roller of the two pressing rollers can rotate and pull the carbon fiber paper, which makes the upper and lower surfaces of the carbon fiber paper subject to different force directions, making it easy to deflect. Utility Model Content

[0004] The utility model aims to solve the problem that only the lower paper pressing roller of the two paper pressing rollers of the H1400 type dipping machine in the prior art can rotate and pull the carbon fiber paper, which makes the upper and lower surfaces of the carbon fiber paper subjected to different forces in different directions and is prone to deviation, and proposes a carbon fiber paper dipping device.

[0012] Preferably, a scale is provided on one side of the cross bar, a pointer is provided on one side of the scale, and the pointer is fixedly connected to one of the chain plates.

[0013] Compared with the prior art, the utility model provides a carbon fiber paper dipping device, which has the following beneficial effects:

[0014] The carbon fiber paper dipping device rotates and installs a paper pressing roller 1 at a fixed position on a dipping machine through two connecting seats, and then swings and rotates the paper pressing roller 2 under the top cylinders of the two connecting seats through two chain plates, so that the vertical distance between the cylinder and the paper pressing roller 1 is always kept constant, and the vertical distance between the cylinder and the paper pressing roller 1 is always kept constant. Then, a series of synchronous transmissions of the pulley 1, the anti-slip transmission belt ring and the pulley 2 are mainly used to synchronously connect the paper pressing roller 1 and the gear 1 in the same direction, and then cooperate with the mutually meshing gear 1 and the gear 2 to rotate the mutually parallel paper pressing roller 1 and the paper pressing roller 2 in opposite directions at all times, so that the magnitude and direction of the pressure applied by the pair of paper pressing rollers to squeeze through the carbon fiber paper are exactly the same as the magnitude and direction of the pressure applied by the pair of paper pressing rollers to squeeze through the carbon fiber paper, that is, the forces applied by the paper pressing roller 1 and the paper pressing roller 2 to squeeze through the two sides of the carbon fiber paper are the same and will not deviate, and the paper pressing roller 1 and the paper pressing roller 2 rotate synchronously to pull the carbon fiber paper, which is more efficient and stable than the single-roller traction in the prior art.
